Add yeast mixture, olive oil, and remaining 1/2 cup warm water and stir until smooth. Stir in enough flour (about 1/2 cup) to make dough come away from sides of bowl.

Holding one edge of dough in the air with both hands and letting bottom just touch the work surface, carefully and quickly move hands around edge of dough (like turning a steering wheel), allowing weight of dought to stretch round to roughly 10 inches.
